The function's name is misleading as one might think it is used
generally to select the boot-mode when in reality it is only used by the
MMC driver to find out in what way it should try reading U-Boot Proper
from a device (either using a filesystem, a raw sector/partition, or an
eMMC boot partition).
Rename it to spl_mmc_boot_mode() to make it more obvious what this
function is about.

Update the driver to support the device tree and the driver model.
Timings and panel parameters are now loaded from the device tree.
The DM code replaces the am335x_lcdpanel structure with
tilcdc_panel_info taken from the linux kernel, as well the management
of additional parameters not covered in the legacy code. In addition,
the am335x_lcdpanel structure contains parameters and operations that
were probably a requirement of the board for which this driver was
developed and which, however, were not developed in the linux kernel.
All this led to rewrite th DM controller initialization code, except
for the pixel clock setting that is executed in a function created in a
previous patch with code taken from the legacy am335xfb_init.
The patch has been tested on a custom board with u-boot 2018.11-rc2 and
the following device-tree configuration:
panel {
compatible = "ti,tilcdc,panel";
pinctrl-names = "default";
pinctrl-0 = <&lcd_enable_pins>;
enable-gpios = <&gpio0 31 0>;

At present if CONFIG_SPL_GPIO_SUPPORT is enabled then the GPIO uclass
is included in SPL/TPL without any control for boards. Some boards may
want to disable this to reduce code size where GPIOs are not needed in
SPL or TPL.
Add a new Kconfig option to permit this. Default it to 'y' so that
existing boards work correctly.
Change existing uses of CONFIG_DM_GPIO to CONFIG_IS_ENABLED(DM_GPIO) to
preserve the current behaviour. Also update the 74x164 GPIO driver since
it cannot build with SPL.
This allows us to remove the hacks in config_uncmd_spl.h and
Makefile.uncmd_spl (eventually those files should be removed).

The commit 1b42ab3eda8a ("ARM: DRA7: Fixup DSPEVE, IVA and GPU clock
frequencies based on OPP") added the core logic to update the kernel
device-tree blob to adjust the DSP, IVA and GPU DPLL clocks based on
a one-time OPP choice selected in U-Boot for most of the DRA7xx/AM57xx
family of SoCs.
The DSPs on DRA76xP/DRA77xP SoCs (DRA76x ACD package SoCs) though
provide a higher performance and can run at a higher clock frequency
of 850 MHz at OPP_HIGH instead of 750 MHz. Fix up the logic to use the
correct clock rates on these SoCs. Note that this higher clock rate is
not applicable to other Jacinto 6 Plus SoCs (DRA75xP/DRA74xP SoCs or
AM574x SoCs) that follow the ABZ package.

The hierarchy of this clocks DT node has changed in newer Linux kernels

This patch disables DM watchdog support for SPL builds and uses

Adjusted WATCHDOG_RESET macro accordingly. Earlier it was pointing
to hw_watchdog_reset. Since CONFIG_WATCHDOG replaces CONFIG_HW_WATCHDOG,
now WATCHDOG_RESET macro points to watchdog_reset. This watchdog_reset
is not defined anywhere for am33xx/omap2 and needs to be defined. Fixed
this by simply calling hw_watchdog_reset in watchdog_reset.
Built and tested on AM335x device (BeagleboneBlack), compile tested for
all other AM33xx/omap2 based boards.

"fastboot flashall" expects "fastboot getvar product" value to be one of
values provided in android-info.txt file (in AOSP), from "require
board=" list. Before this patch, "am57xx" is returned for all AM57xx
based boards, as it's set in $board env var from SYS_BOARD in
board/ti/am57xx/Kconfig file, which is used for default implementation
of "fastboot getvar product".
In order to fix that inconsistency, let's do next:
1. In U-Boot: override fastboot.product, reusing the value from
$board_name
2. In AOSP: provide values for all AM57xx boards we can use to
device/ti/beagle_x15/board-info.txt file
This way requirements check in "fastboot flashall" will work as
expected, verifying that user tries to flash images to the board which
those images were built for.

The USE_TINY_PRINTF symbol only changes things within SPL and TPL
builds, so make it depend on that support. Next, make it default as
within these cases we should rarely have need of more advanced print
formats outside of the debug context.
To do this, in a few cases we need to correct our Kconfig dependencies
as we had cases of non-SPL targets select'ing this symbol. Finally, in
the case of a few boards we really do need the full printf
functionality.

The board_early_init_f() inits clock before initing pinmux. However,
the clock configuration code might need to adjust PMIC settings of a
PMIC on I2C bus (e.g. board/ti/am335x/board.c does that). If the I2C
bus pin muxing is not configured before attempting to communicate
with the PMIC, the communication will silently fail and the prcm_init()
may configure fast enough CPU clock that the default voltage provided
by the PMIC would be insufficient and the platform would become
unstable.
